    Cogged SC Belt Mod

    I've had an interest in making a reality of my idea and have the means to get it done. I was very suprised R&D did not go this route, at least as an option, but can also see the cost factor and keeping the same belt would keep it down. Ever since i picked up my ski, i wondered why the heck a serpentine belt was in this application. I can only sum it up to cost/ease and less issues for lack of maintenance.

    I really need to be careful around this area when applying my corrosion protection of choice, Fluid Film, as it will make the belt slip if sprayed.

    Anybody interested?

    I would expect more belt failures with the cog. Also, there does not appear to be much if any slip with the stock pulley, What advantage would the cog setup have over stock?

    timing belts on cars have "teeth". On honda's they are good for 90,000-110,000 miles.

    Seem like a good idea but it could possibly cause more drag and we need every once of HP we can get.

    Without knowing anything about the Kawi setup, I assume that they are relying on slippage in the serpentine belt to act like a clutch when the ski goes airborne. like yam's sprag and doo's washers

    How can a belt slip when the ski is airborne and not slip when it's not?
    Completely different kind of blower on the Kawi verses the Seadoo or Yamaha. The Kawi also has a relief valve.
